In chemistry, a molecule or ion is said to be chiral if it cannot be superposed on to its mirror image by any combination of rotations, translations, or conformational changes. A chiral molecule or ion exists in two forms, called enantiomers, that are mirror images of each other; they are often distinguished as either ‘right-handed’ or ‘left-handed’ by their absolute configuration. Enantiomers exhibit similar physical and chemical properties, except when interacting with polarized light and reacting with other chiral compounds, respectively.
